Character name: Lux Nightingale
I did Ascalon Catacombs, flaming scepters way, around 2:31(UTC-03:00), and received only 20 tokens. It took us around one hour and things went smoothly.. Until the reward that is. It was the first time we did flaming spceters today and it is the first time this bug happenned with me.
Hope you guys fix it soon.
